We repair and replace wired thermostats and smart models from Honeywell, ecobee and Google Nest, and we test the wiring and the control board at the equipment, not just the device on the wall.
In many older San Diego homes the thermostat wire was run decades ago for a simple heat-only furnace, and it may not have the extra conductor a smart thermostat needs for steady power. That's a common reason a new ecobee or Google Nest keeps rebooting. Placement matters too. A thermostat on a wall that gets afternoon sun, or one near a kitchen or a drafty hallway in a beach cottage, reads the wrong temperature and runs the system too much or too little. We check the wiring, the location and the equipment so the fix lasts.
We offer thermostat repair across San Diego, La Jolla and Chula Vista. Choose your area:
Not always. Dead batteries, a tripped breaker, a blown fuse on the furnace control board or a safety switch on a clogged condensate drain can all leave the thermostat dark. We find out which before replacing anything.
Most of the time it isn't getting steady power, often because there is no common wire or a wire is loose. We check the wiring at the thermostat and at the equipment and fix the power supply so it stays on.
Yes. Many two-story homes have zoning or two separate systems. We test each thermostat, the zone dampers and the zone control board to find which part is causing the problem.
